My dad once told me how to shoot explosive rounds from my BB/pellet gun. I was amazed to see how well it worked, and I finally have a chance to show it off. First of all: DON'T BE DUMB AND BURN SOMETHING DOWN!!!! If you do, I am not liable. It shouldn't happen as long as your careful.
Anyway, lets get to the fun stuff...
Step 1: Get Some Strike Anywhere Matches.
Step 2: Get Your Matches Out, and Get Your BB/pellet Gun Out.
Step 3: Put the Match in the BB/pellet Gun.
Step 4: Now Shoot It.
Final notes: Sometimes the match will fly very strangely and go in a random direction, so be careful. (this happens often because the match is going too fast, an is obviously not very aerodynamic. use fewer pumps if this happens consistantly)
Sometimes, rather than popping like how it should, it will just light on fire and burn stuff. Dangerous, but it gives you some ideas...
If it hits, but doesn't light or pop, get closer. The closer to the target the better.
Try taping sandpaper to the end of your gun. I've had the match light in mid-air, making tracer rounds! (do this only with 1 or 2 pumps in it)
Sorry for such a long instructable. Just put a strike anywhere match in a BB gun and fire it, basically. Have fun.
Look for some of my most-likely-similar-upcoming-instructables!
